Recent results on Dark Sector Searches at Belle-II

The Belle II experiment provides a unique opportunity to explore the dark sector, offering exceptional sensitivity to a broad class of models that propose light dark matter and dark mediators with masses between a few \(\mathrm{MeV}/c^2\) and \(\mathrm{GeV}/c^2\). This paper reports the latest world-leading physics results from Belle II searches for an \(X\) resonance decaying into two muons, interpretable both as a \(Z'\) boson and a muonphilic dark scalar particle; long-lived (pseudo)scalars produced in \(B\) meson decays; inelastic dark matter in association with a dark Higgs boson as well as future prospects for other dark sector searches.
